  • Patent number: 7282679
    Abstract: In order to make it possible to produce a secure and permanent contact connection between an electrical conductor made from a soft material, in particular an aluminum conductor, and a contact element made from a harder material, the conductor is encapsulated at least partially in a contact region by an electrically conductive material. The electrically conductive material is harder than the soft material of the conductor. The electrically conductive material is applied with the aid of a thermal spraying process, with the result that there is a pressure-free electrical connection between the soft material and the sprayed-on material. Electrical contact is made with the contact element indirectly via the sprayed-on material. The thermal encapsulation by the spraying in the contact region makes it possible for a reliable electrical contact to be made even in the case of soft materials having a tendency towards cold flow.

  • Publication number: 20040238763
    Abstract: An emitting source capable of radiating substantial energy in the near infrared spectrum and suitable for use in non-dispersive infrared gas analyzers or other devices is described. Operation can be steady state (DC) or pulsed at high frequency with excellent modulation characteristics. The device consists of a tungsten filament mounted across the pins of a small transistor outline header and centered at the focal point of a parabolic or other shaped reflector. The header assembly is enclosed by a resistance-welded cap and window assembly having a specially sealed sapphire or other suitable IR transmissive window. Fundamental to the operation of the inventive IR emitter is the incorporation of a getter within the header package configured to prevent oxidation degradation of the tungsten filament. An inert gas backfill limits filament evaporation and further extends apparatus lifetime.

  • Publication number: 20040217111
    Abstract: The invention relates to an infrared radiation source having at least one electrical heat conductor situated in a long, two-ended casing tube made of quartz glass, the casing tube having at least one elevation made of quartz glass on its wall which faces the at least one heat conductor, which locally reduces the inner diameter of the casing tube. At least one heat conductor is designed as a heating coil. The casing tube has a constant outer diameter in the region of the heating coil, the elevation has a convex shape on its surface facing the heating coil, and the heating coil contacts the elevation only at the highest point of the elevation.

  • Publication number: 20040149713
    Abstract: The present invention provides a soldering iron with a graphite tip having two separate halves that are electrically isolated from one another. When both halves of the tip are applied to an electrically conductive material, such as the material to be soldered, an electrical circuit between the tip halves and an electrical power source is completed. Therefore, the tip can reach operating temperatures quickly. When the tip is removed from the joint, the electrical circuit is broken and the tip material may quickly cool to a temperature safe for human contact. The tip material permits higher power outputs than other battery operated portable soldering irons and permits over 300 joints for each full charge.

  • Publication number: 20040104216
    Abstract: A method of fracturing or breaking rock includes the step of directing high intensity white light (radiation) at the rock to induce thermal stress sufficient to fracture the rock. The intensity of the energy source may be varied to control the manner in which the rock fractures. An approach for generating high intensity white light includes an elongate arc chamber and an elongate concave reflector. The arc chamber and reflector may be shielded from airborne particulate matter by an air shield or a rotating or reciprocating translucent shield.
